Enable ThinkPad W520 Nvidia Quadro 1000M at Ubuntu


The following are the steps of what you have to do to enable Nvidia Quadro 1000M on ThinkPad W520:
1. You need to disable Optimus in the BIOS and set the card to discrete mode.
2. You also need to install Ubuntu and after that activate Nvidia propriety driver under “Additional Drivers”
3. Then, reboot your laptop and run nvidia-xconfig
4. Follow it by editing /etc/X11/xorg.conf and add BusId “PCI:1:1:0” to the “Device” section.
You have to blacklist the nouveau driver by adding:
blacklist vga16fb
blacklist nouveau
blacklist rivafb
blacklist nvidiafb
blacklist rivatv
to /etc/modprobe.d/blacklist.conf
5. Use the following symbolic link:
Sudo ln –s /var/lib/dkms/nvidia-current/2.70.41.06/build/nvidia.ko/lib/modules/2.6.38-8-generic/kernel/drivers/video/nvidia/nvidia.ko sudo depmod -aq
to make the Nvidia kernel driver loadable
6. Finish it by rebooting your laptop.
